Depth is 70 mm, width 72 mm (4 MW), height 90 mm. Mounting position is any orientation — no derating needed for horizontal or inverted placement. Installation depth matches the 70 mm body depth; no extra clearance needed behind the rail. The silicon-free construction matters if this goes into a paint shop or potting line where silicone outgassing causes adhesion failures. The 63 A rating is at 40 °C ambient; the thermal power dissipation per pole is 3.9 W in hot operating state — factor that into enclosure heat rise if you're packing 4+ units side by side. The 300 mA trip threshold is Type AC (sinusoidal AC residual currents only), not suitable for pulsed DC or smoothed DC fault currents — if your load includes VFDs, UPS, or rectifiers, you need Type A or B. The 6 kA SCCR is the conditional rating per IEC 61008-1 at 0.8 kA let-through; the maximum permissible series fuse is 80 A. The I²t let-through is 110 000 A²·s, and the peak let-through current is 7 100 A — these matter for selectivity coordination with upstream MCBs. Mechanical life is 2 000 operating cycles typical — adequate for a distribution board, not for frequent switching duty.","metaTitle":"Siemens 5SV5646-0 SENTRON RCCB, 4P, 63 A, 300 mA, Type AC","metaDescription":"Siemens 5SV5646-0 SENTRON 4-pole RCCB, 63 A rated, 300 mA trip, Type AC, 6 kA SCCR, 50 Hz, 230/400 V.
